I would also like to introduce a little known contemporary author to you (see end of post). Scrotivius (origin unknown) wrote extensively on this campaign. That he lived in Rome is not doubted, but his sympathies are far less certain. From time to time I will quote his words.

Roman deployment is typical: A standard consular army deployment of legions in the centre with cavalry on the wings. Peter and I do not hold with three quarters of the cavalry being on one (left) wing. As a third of the allies were detailed off as extraordinarii, we believe it is just as likely that these formed up with the 'Romans' - as most allies had been colonised by the Romans, they may actually have been so - equalling up the deployment exactly. I have no direct evidence that this is true or was ever done; I just find it hard to believe that a comparable 25% to 75% wing deployment is not mentioned when it comes to Hannibal's deployments - he seems to have deployed roughly 50% - 50%.
The Roman centre. Comprising the meat grinder - 2 legions with their ala in triple acies formation(Ager Proelii style).
Historically, a consular army had a frontage of about one mile.
Another shot of the centre from the front. Velites, Hastati, Principes, Triarii.
P. Scipio can be seen giving encouragement from the rear.
A cavalry wing. In this case the right, comprising Roman equites and the extraordinarii.
The Carthaginians have deployed their army, comprising African and Iberian troops only (the Gauls in these parts are not too friendly!), with an infantry centre and two equal cavalry wings. Spanish infantry are deployed to take the brunt of the fighting, whilst the deployment of Libyan spearmen and elephants has the look of 'Trebbia' about it. Hannibal has chosen to put all of his Numidian cavalry on the left and his Spanish cavalry on the right.
Spanish cavalry outnumber their Roman counterparts by 2 : 1.
Elephants and Lybyan spearmen.
The Spanish infantry. The shield markers denote 'solliferrum at the ready'.
A mirror of the right except for Numidian instead of Spanish cavalry.
Command quality, and the disparity of morale chips, may be the key to this battle. The Romans rolled low command quality rolls and have two D10 and two D8 command group officers. The Carthaginians rolled high and have three D12 and one D10 command group commanders.
Scrotivius wrote: "On the morning of the battle Publius encouraged his troops with brave words and vows not to let the despoiler of Sagentum pass. Hannibal, for his part, stood before his troops and merely raised the skirt of his tunic, winked and smiled: The roar of the Carthaginians echoed across the Alps."
